I have a 50 gallon (36x18) tank that I used for my first setup. Based on both my examination and the input of some club members, I don't think it is safe to hold water due to a chip in the mating portion of one of the long panels. It's otherwise in good shape though, so if anyone has a use for a larger terrarium, they are welcome to have it, seems a shame to just chuck it. Located in 08065, but I travel to Linden weekly and work in the Trenton area, so I can haul it up if someone wants to meet further north.
